The COP400 or COPS II or simply COPS (Controller Oriented Processor System II) was a family of 4-bit microcontrollers developed by National Semiconductor. The family was introduced a year after the COPS I in 1977. Components in the COPS II were made in nMOS and CMOS technology instead of pMOS as used in COPS I. The COPS II obsoleted the COPS I family soon after release.
In late 1981 National Semiconductor introduced a number of dual-core microcontrollers, one of the earliest instances of multiple CPUs in on single integrated circuit.

Dual cores[edit]
Announced in 1981 and manufactured later that year, National introduced a number of dual-core microcontrollers. While primitive by today's standard (no notion of mutual exclusion), those chips were true dual core - perform calculations independently of each other and capable of accessing the same ROM, RAM, and I/O ports.
